I am doing a project, but am struggling to find relationships or formulae between my dependent variables (angular velocity, displacement, acceleration of the disc and kinetic energy of the system) and my independent variables (falling masses and then the number of winds) or any other relationships that can occur. Below is a picture of my setup. It works by winding the disc, and then releasing it to unwind. The disc has two holes which the strings go through.
Thank you.
Thank you.
